Lately there's been a lot of talk about parallel processing, sharding, L2, which has higher TPS, lower fees, and bigger subsidies... It looks quite lively, but I still have my old problem: first, check how they handle fund security, whether they've filled the cross-chain/bridge pitfalls, and if something really happens, can I withdraw smoothly. To put it simply, no matter how good the performance is, if the exit path is a mess, I wouldn't dare to put too much in. My friend also complains, "You buy a coin like you're checking a rental contract," fine... Anyway, I prefer to go slow, keeping an eye on small metrics like TVL, fee rates, and retention, as long as they don't explode, and avoid being led astray by mudslinging.
